So I just received a used macbook that has something stuck in the headphone port. What this means is that os x wants to use the optical out (digital) and once it does that there is no way to use the internal speakers. And, because it is stuck, I can't use headphones either. Temporarily, I am trying to use an old USB external Creative sound card for my audio, but when I plug it in all it does is recognize it. I tried plugging into every port but nothing. ANy ideas?
